The riot template engine
``sh`
npm install @n8n-io/riot-tmpl --save
From v2.4.2, bower is not supported.
Three ways:
- Expressions: tmpl('{ value }', data).
Returns the result of evaluated expression as a raw object.
- Templates: tmpl('Hi { name } { surname }', data).
Returns a string with evaluated expressions.
- Filters: tmpl('{ show: !done, highlight: active }', data).
Returns a space separated list of trueish keys (mainly used for setting html classes), e.g. "show highlight".
`js`
tmpl('{ title || "Untitled" }', data)
tmpl('Results are { results ? "ready" : "loading" }', data)
tmpl('Today is { new Date() }', data)
tmpl('{ message.length > 140 && "Message is too long" }', data)
tmpl('This item got { Math.round(rating) } stars', data)
tmpl('{ title }
{ body }', data)
In templates (as opposed to single expressions) all falsy values except zero (undefined/null/false) will default to empty string:
`js
tmpl('{ undefined } - { false } - { null } - { 0 }', {})
// will return: " - - - 0"
tmpl('{}') // undefined
tmpl('{ false }', {}) // false
tmpl('{ null }', {}) // null
tmpl('{ 0 }', {}) // 0
`
* Brackets can not contain characters in the set [\x00-\x1F<>a-zA-Z0-9'",;\\]
* No comments in expressions, the compiler is the only that strip comments
* Attributes with expressions containing
